Douglas Squirrel

Sciuridae Sciurinae

Douglas squirrels are found from southwest British Columbia, Canada and along the coastline as far south as Northern California. They are found in coniferous forests (such as Douglas fir, Western Hemlock, Sitka Spruce, Shore Pine and others) and prefer old-growth or mature second growth forest. They feed on the seeds from these trees as well as berries, mushrooms, bird eggs, acorns and fruits.

The color and nesting behavior of Douglas squirrels varies dependent on season. In summer season they are a grayish-brown, have pale orange on the chest and belly with brown feet and legs. They nest in ball-shaped nests made of moss and small pieces of bark and twigs made in the trees. In the winter the coat is browner, the chest and belly are grayer and they use holes in trees for nesting. They also develop ear tufts in winter months and nest inside holes of trees. They are noisier than most species of squirrels, often using their loud voices to warn other animals of danger.

Their body length is approximately 6-7 inches long, with a bushy tail of about 5-7 inches. The tail is somewhat wide and flat with a black tip. They have white rings around their eyes. Average weight is between 150 and 300 grams. Mating can occur as early as February. Gestation is approximately 4 weeks. Litter size is typically 4-6 kits (or young) per litter. Douglas squirrels are very territorial. In winter each squirrel occupies a territory of around 2.5 acres. During breeding season a mated pair will defend a single territory together. Groups that are seen together in the summer are likely juveniles from a single litter.

While Douglas squirrels are primarily tree dwellers, they can enter home structures in search of food or shelter for a new den site. They will often gnaw through wood around small existing holes to expand the opening and gain entry. Invasion into a human living space is less than desirable for many reasons. These animals can carry parasites that can affect human health and can be very destructive to property as well. They can shred ductwork, damage or destroy insulation, chew on structure wiring, and cause health and sanitation issues due to excrement they leave.

Important prevention measures include:

1. Remove available food sources including bird feeders and fallen tree needles and debris.
2. Seal any openings into the structure that could offer an entrance into the structure. This includes all openings such as attic vents, chimneys and cracks under eaves.

While these preventative measures may help, if you have an infestation and need help with control, a call to Long Pest Control can develop an Integrated Pest Control program to eliminate the sightings and provide an environment free of unwanted pests year round.
